Keith Shepherd of the Soil-Plant Spectral Diagnostics Laboratory of the World Agroforestry Centre (ICRAF) in Nairobi, Kenya has written an interesting blog post for World Soil Day (5 December 2014). He also points out that 2015 is both the International Year of Light and Light-based Technologies (IYL 2015) and the International Year of Soils (IYS). Keith goes on to describe how light is being used to revolutionise the measurement of soil health.
